ASSIGNOR 'lO DUPLEX Specification of Letters Patent. Application filed September 18, 1906. Serial No. 336,052.

iatented May 14,1907.

.To 1 whom it may concern:

Be it known that I, HENRY F. BEOHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Inking Mechanism; and I hereby declare that the following is a full, clear, and exact description thereo reference being had to the accompanymg drawings, which form part of this specification.

This invention is an improvement in inking apparatus for printing presses and particularly in, the means for operating the vibrator rollers; and specifically is an improve-. ment upon the inking apparatus shown in my Patent No. 823,098, dated June 12, 1906; and its object is to enable one or more vibrator rollers to be moved endwise sin1ul tane-' ously and in opposite directionsby one actuating device; and also to enable one actuating device to operate two axially alined sets of vibrator rollers.

The device in brief comprises one or more parallel vibrator bars meshing with an inter- Fig. 1

'mediate pinion, which also meshes with a recipro-catory rack bar lying at right angles to the vibrator bars and operated by a pitman connection, or other suitable device from an adjacent gear wheel, which may be on or operated from one of the distributing'roll shafts, or the ink-drum shaft. The vibrator bars extend in alinement with the vibrator rolls, when the latter are in operative position, and are provided with devices adapted to engage the ends ofthe adjacent vibrating rollers so as to vibrate the latter when the rack bar is T. ie" invention will be fully understood from the. accompanying drawings and the following explanation thereoff-the said drawin s however are not drawn on a workk ing sca e, but will suilice to enable a m'echanic to fully understand the construction and to apply it to the inking mechanism ola printin press and particularly to the mech anism illustrated in my aforesaid patent.

In the drawings l igure 1- is a detail view of part of the inkin mechanism of a printing press with the nov l vibratory-roll operating mechanism; anill ig. 2 is a top plan view of In the drawings 1-, 1 and 1. indicate vibrator rolls which are adapted to co-act with the ink drum 2, for distributing the ink, this arrangement of rolls and drum being well understood. i

Each vibrator-roll is provided with a grooved collar (1 1 and 1*) for enga empnt with the mechanism for vibratingt e r0 ls. rollers 1 and 1 are engaged by pins3 and 3 on arms 4 on the end of a supported in axial alinement with the rolls,

and is'adap ted to be recipropated, longitudinal'ly of the rolls, by means-ofrach-teeth 4*, en aging a pinion 6, which is journaled in a brac cat 7, attached to the main rains and .upon which bracket the bar 4 is,

ported. p 7

Beside bar 4, is a similar bar b, whose innerend is bent as at 5 so as not to conflict with the arms 4 on bar 4, and is provided with a pin 5 adapted to engage intermediate roller 1. Vibrator bar 5 1s also provided with a toothed portion 5 which engages the pinion 6 at the side opposite bar 4, consequently when the pinion 6 is rotated the vibrator bars 4 and 5, will be re-v ciprocated in opposite directions,

pinion 6, reci )rocatory movements will imparted to t e vibrator bars vibrator rollersFl, l and 1 rollers 1,1". l Mounted on bracket 7 is a rack-bar 6 which lies at right angles to vibrator bars 4 and 5, and engages the pinion 6 belowth'e bars 4 and 5,-and by reciprocating'rackbar 6 bars 4 and 5, will also be reci rocated at right angles to bar '6. The rac bar 6 may be operated by means of a 'pitman 6, pivotally connected to said bar andito a crank-pin 6 on a car 6" which may be driven from the ink-drum or from any other continuously rotating shaft, or the said-gear could be placed on the shaft of one of the rotating rolls adjacent the vibrator actuating, mechanism. y l/Vhere two sets of inking mechanisms are arranged end to end and closely adj acent, onemecharnsm can be em on both sides of the bracket 7, and providin As shown the collars 1F and 1 on" bar 4, which bar is also supthe collar 1 ntheand conse quently by imparting rotatory movements to,

be. 4, and 5, and but vibrator roller 1 will move I oppositely to vibrator and can readily be applie sitelly I mes .ing with both bars and means sides of said gear,

each end of bar 4 with arms 41 and forming 1 each end of bar 5 alike, so that they can enthe vibrator rollers in each set or" inking mecln'inism, as shown.

Obviously by simply preferably shaping the'ends of the vibrator bars 4 and 5, they can each be caused to simultaneously operate two or more vibratory rollers at each end or both ends, and therefore I do not wish to be restricted to the, particular construction and arrangement of the ends of the vibrator bars, and the particular number and arrangement of vibrator .rollers operated thereby, illustrated inv the drawings.

Thedevice is very sim lo and eii'ective to many of the inking mechanisms now in, use. The vibratory rollers 1, 1 and 1 may be mounted upon swinging supports as shown in my said patent, so that they can be thrown into or out of contact with the i11k-drum 2, being shown in contact therewith in full lines in Fig. 1, and out of contact therewith in dotted lines.

With this mechanism it is an easy matter to impart any desired length of endwisc.

movement to the vibrator rollers, and any desired rapidity of reciprocation thereto, relative to the surface speed of the drum, this being merely a matterof properly proportioning'the gearing.

Having described my invention what i claim as new and desire to secure by Letters Patent is:

1. In an inking mechanism, the combination of vibrator rollers, a pair of vibrator bars respectively engaging d1ierent rollers, a gear meshing with both bars, and means for imparting movements to said gear.

2. In an inking mechanism, the combination of oppositely reciprocating vibrator rollers, a pair of oppositely reciprocating bars engaging the oppositely reciprocating vibrators, a rotatory gear meshing with both bars and means for operating said gear.
